Abstract

The embodiment of the invention discloses a boundary generation method and device of a target place, electronic equipment and a storage medium. The method comprises the steps that a target track with the target place as a destination in a historical time period is acquired; candidate track points located in a target place are extracted from the target track; performing density clustering on the candidate track points to obtain target track points; and determining a convex hull of a point set formed by the target track points, and determining the convex hull as the boundary of the target place. According to the technical scheme, the boundary of the target place can be mined through the trajectory data in the historical time period, and the accuracy is improved while the cost is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of geographic information, and in particular, to a method, device, electronic device and storage medium for generating a boundary of a target place. Background technique [0002] With the development of location-based services (LBS), more and more application software integrates the service capabilities related to electronic maps. For example, users can search for points of interest (POI) in the electronic map through map navigation application software or online car-hailing application software, and plan a navigation route to the POI. It is a real-world residential area, in-building bottom business, subway station, parking lot and other places. [0003] Taking the navigation service scenario as an example, in the process of guiding the navigation object to enter a target place such as a parking lot that covers a certain geographical area, it is necessary to use the boundary of the target place to ...
